Gahnospinel and Amazonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Gahnospinel and Amazonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gahnospinel and Amazonite Optical Properties during the identification of gemstone. Specific gravity of Gahnospinel is 2.55-2.57 whereas that of Amazonite is 2.55-2.57.
